Thank you fixkick, this is great information, the visuals are extremely helpful! Is the TV stop screw the same as the idle adjustment screw, i.e. the one sticking out diagonally next to the dashpot on the back of the TB? Is there any other screw that I can turn to adjust idle on the TB? I thought this screw should never be touched on 91+? (I have an 89 but I'm just wondering because you said for 91+ it's CCW to add air...). When I got my car back from the shop a few weeks ago the hot idle was at 600 and the accelerator pedal was getting stuck sometimes (i.e. the butterfly valve was closing too tight and getting stuck) so I turned this screw clockwise 1/4 but it didn't change the idle, so I turned it another 1/4 and the idle still didn't change so I turned it like a full 1.5 turns or so, and it finally raised the idle to 800 but now the idle seems weird, it only gets to 800 after like 30 minutes of driving, as if it's taking forever to warm up or something... after warming up it stays at 1000 for half an hour of driving before it finally drops to 800... any thoughts?
